Claims

[Scope of Claim for Utility Model Registration] A connecting interlocking valve that is installed between lubricating oil pipes and connects a pair of opposing check valves to communicate the oil passages, wherein one check valve is connected to the other check valve. A cylindrical housing has a contact surface at the tip to which the connection seal of the check valve is brought into close contact, and a valve seat provided on the back side of the contact surface slides from the contact surface to the valve body which is sealed by the biasing force of a spring. the other check valve has a cylindrical housing having a valve seat part in the middle thereof, and a tip end thereof is a contact surface of the one check valve. A connecting seal that is formed smaller and seals the opening provided at the tip is provided on the periphery of the opening, is slidably fitted to the tip of the housing of the other check valve, and is attached by a spring toward the tip. A sealing cylinder that is biased and protrudes a predetermined amount from the tip of the housing, a valve body that seals the valve seat of the other check valve with the biasing force of a spring, and a shaft that is inserted from the valve body into the valve seat. a valve portion disposed inwardly from the tip of the sealing cylinder through the check valve and having a pressure-receiving surface wider than the front end of the abutment rod; When the connection seal is brought into contact with the contact surface in a state where it does not retreat, both valve bodies have a movement range shorter than the protrusion length of the sealing cylinder on the rear side, and there is a gap between the abutment rod and the pressure receiving surface. An interlocking valve for connection, characterized by being provided with.
